Without digging out a bunch of old text books, if I remember correctly, an engine uses fuel to create energy which is converted into mechanical work, while a motor converts external energy into mechanical work.

Therefore, the big block of metal, under the hood, would be an engine; while, as stchman suggested, the blower is a motor.
